Bundle twisted-pair cable

Abstract

A cable includes a plurality of twisted pairs of conductors in a dense hexagonal matrix-like form defining thereof horizontal rows and oblique columns with each other in a rectangular coordinate system wherein the twisted pairs in the same row have the same twist direction while having opposite twist directions with those in the two neighboring rows aside, and wherein for each row there is a ninety degrees phase shift between every adjacent two pairs and for each column there is a non-ninety degrees phase shift between every adjacent two pairs.

1. A cable includes a plurality of twisted pairs of conductors in a dense matrix-like form defining thereof horizontal rows and oblique columns with each other in a rectangular coordinate system wherein the twisted pairs in the same row have the same twist direction while having opposite twist directions with those in the two neighboring rows aside, and wherein for each row there is a local phase shift between every adjacent two pairs by following an equation of [60+(α/3)] or [120−(α/3)], and an initial arrangement in a first row has a global phase shift of [(5α/3)−60] and in a second row adjacent to said first row, has a global phase shift of −[(5α/3)−60], wherein α is an angle defined by every adjacent three twisted pairs which form an acute triangular cross-section. 
   
   
     2. The cable as described in  claim 1 , wherein each of said rows includes at least two twisted pairs of conductors. 
   
   
     3. The cable as described in  claim 2 , wherein said cable defines a hexagonal form. 
   
   
     4. The cable as described in  claim 2 , wherein α is equal to 60 degrees. 
   
   
     5. The cable as described in  claim 1 , wherein the cable includes at least five twisted pairs of conductors. 
   
   
     6. The cable as described in  claim 5 , wherein said cable defines a hexagonal form. 
   
   
     7. The cable as described in  claim 5 , wherein α is equal to 60 degrees. 
   
   
     8. The cable as described in  claim 1 , wherein each of said twisted pairs is not further twisted with any neighboring twisted pairs. 
   
   
     9. The cable as described in  claim 8 , wherein said cable defines a hexagonal form. 
   
   
     10. The cable as described in  claim 8 , wherein α is equal to 60 degrees. 
   
   
     11. A cable includes a plurality of twisted pairs of conductors in a dense matrix-like form defining thereof horizontal rows and oblique columns with each other in a rectangular coordinate system wherein the twisted pairs in the same row have the same twist direction while having opposite twist directions with those in the two neighboring rows aside, and wherein for each row there is a local phase shift between every adjacent two pairs by following an equation of [45+(α/2)] or [135−(α/2)] degrees and a global phase shift angle under an equation of +[(3α/2)−45] or −[(3α/2)−45] wherein α is an angle defined by every adjacent three twisted pairs which form an acute triangular cross-section. 
   
   
     12. The cable as described in  claim 11 , wherein there is a global phase shift angle of +2[(3α/2)−45] or −2[(3α/2)−45] between the twisted pairs of every other row. 
   
   
     13. The cable as described in  claim 12 , wherein α is equal to 75 degrees. 
   
   
     14. The cable as described in  claim 11 , wherein each of said rows includes at least two twisted pairs of conductors. 
   
   
     15. The cable as described in  claim 11 , wherein the cable includes at least five twisted pairs of conductors. 
   
   
     16. The cable as described in  claim 11 , wherein each of said twisted pairs is not further twisted with any neighboring twisted pairs.
